Abstract
Studying amorphous ferromagnetic ribbons, a system for helical stress annealing has been performed. The angular deformation against the time at constant applied torque, torsional creep, and the relaxation curves can be obtained. The helical induced magnetic anisotropy is also measured. During the annealing processes the magnetic behaviour can be observed for an annealing temperature below the Curie temperature. The Mz against Hz and Mz against Hy (inverse Wiedemann effect) hysteresis loops are measured.
